Osteosclerosis due to endemic fluorosis.

Endemic water borne fluorosis is a public health problem in Isparta, a city located in southern Turkey. In order to investigate the association between osteosclerosis and fluorosis, we retrospectively screened the results of lumbar spine and femur neck bone mineral density (BMD) of 1500 patients who were examined before, for any reason in between 2001-2003. Sixty nine patients (67 females and 2 males, mean age 52.6+/-10.2) with vertebra T-scores>or=+2 were found only except a patient with osteoid osteoma in the femur neck (femur T-score+6.64). Thirty-four of the patients could be reexamined with lateral vertebra BMD and investigated for fluorosis and the other etiologic causes of osteosclerosis. Of 34 patients, 14 had either mottled tooth enamel or urine fluoride level greater than 1.5 mg/l. Other etiologic causes were hypothyroidism (2), hypoparathyroidism (1), history of lumbar fracture (1), use of retinoids (1), vitamin D (7), oral calcium preparations (9), and bisphosphanates (3). Lateral lumbar vertebral T-score was greater than+2 in 12 patients (35.3%). Femur T-score was greater than+2 in 7 patients (20.6%). Fourteen patients (41.2%) had lateral vertebral or femur T-score>or=+2. Five (35.7%) of these patients had signs of fluorosis, as discussed before. Mean body mass index of individuals with fluorosis was 36.4+/-7.9 and this result was significantly higher than other osteosclerotic subjects (31.6+/-4.4). In conclusion we believe that approximately one third of the osteosclerosis in our region was due to endemic skeletal fluorosis and obesity may enhance this osteosclerotic type bone changes in endemic fluorosis.

Percutaneous treatment of Wirsung's duct stenosis secondary to chronic pancreatitis: balloon dilatation and insertion of a plastic stent.

Chronic pancreatitis is one of the indications for pancreatic duct stenting. The success rate of endoscopic stenting of the pancreatic duct is very high (98%). Reports of percutaneous stenting of the Wirsung's duct are very sparse. We present a case with Wirsung's duct stenosis secondary to chronic pancreatitis, which was treated by percutaneous antegrade balloon dilatation and insertion of a plastic stent. We also report on the long-term follow-up of this patient.

Prenatal diagnosis of intracranial pial arteriovenous fistula and endovascular treatment during the neonatal period.

We present a case with prenatal diagnosis of an intracranial high-flow pial arteriovenous fistula that was draining into the vein of Galen in the third trimester of pregnancy. The child was treated by transcatheter embolization with N-butyl 2-cyanoacrylate (NBCA) via the umbilical artery in the early neonatal period due to intractable cardiac failure. Hydrocephalus developed and a ventriculoperitoneal shunt was placed. At the time this report was prepared, the patient was 20 months old and without cardiac failure, but with a delay in neurological development. Prenatal diagnosis and endovascular treatment in the early neonatal period is important in preventing heart failure and resultant mortality due to such high-flow vascular malformations. To the best of our knowledge, the combination of prenatal diagnosis of an intracranial high-flow pial arteriovenous fistula draining into the vein of Galen and endovascular treatment in the early neonatal period is presented here for the first time.

[Pneumosinus dilatans].

Pneumosinus dilatans is a localized abnormal dilatation of paranasal sinuses which contains only air and is covered with normal epithelium. We presented the X-ray, CT and MRI findings of three cases with pneumosinus dilatans secondary to arachnoid cyst and meningioma. When evaluating the patients with long-lasting symptoms, pneumosinus dilatans should be considered.

[Incidence of left renal vein anomalies in routine abdominal CT scans].

PURPOSE: To study the appearance and incidence of left renal vein anomalies in abdominal CT examinations. MATERIALS AND METHODS: One thousand and three abdominal CT examinations were reviewed retrospectively for the presence of left renal vein anomalies. Nineteen CT scans were excluded from the study because of technical or patient-dependent factors. The course of the left renal vein was assessed on the CT slices to detect any anomalies. RESULTS: Left renal vein anomaly was detected in 32 (3.2%) of 984 cases. Twenty-three (2.3%) of them were a retroaortic and 9 (0.9%) of them were a circumaortic left renal vein. CONCLUSION: It is important to detect left renal vein anomalies before retroperitoneal surgery or interventional procedures. These anomalies can be identified in routine abdominal CT examinations with a careful inspection.

Percutaneous drainage of abdominal abcess.

The mortality in undrained abdominal abscesses is high with a mortality rate ranging between 45 and 100%. The outcome in abdominal abscesses, however, has improved due to advances in image guided percutaneous interventional techniques. The main indications for the catheter drainage include treatment or palliation of sepsis associated with an infected fluid collection, and alleviation of the symptoms that may be caused by fluid collections by virtue of their size, like pancreatic pseudocele or lymphocele. The single liver abscesses may be drained with ultrasound guidance only, whereas the multiple abscesses usually require computed tomography (CT) guidance and placement of multiple catheters. The pancreatic abscesses are generally drained routinely and urgently. Non-infected pancreatic pseudocysts may be simply observed unless they are symptomatic or cause problems such as pain or obstruction of the biliary or the gastrointestinal tract. Percutaneous routes that have been described to drain pelvic abscesses include transrectal or transvaginal approach with sonographic guidance, a transgluteal, paracoccygeal-infragluteal, or perineal approach through the greater sciatic foramen with CT guidance. Both the renal and the perirenal abscesses are amenable to percutaneous drainage. Percutaneous drainage provides an effective and safe alternative to more invasive surgical drainage in most patients with psoas abscesses as well.
